Updating is highly recommend as this contains a lot of bug fixes and improvements as well as security fixes (CVE-2014-8321, CVE-2014-8322, CVE-2014-8323 and CVE-2014-8324). More details can be found in the blog.

Changelog:

Airodump-ng should be able to parse the canonical oui file.

Airodump-ng: Fixed GPS stack overflow.

Airodump-ng: Fixed stopping cleanly with Ctrl-C.

Airmon-zc: better handling for when modules are not available (incomplete)

Airmon-zc: users can now start the monitor interface again to change channels

Seems more stable, but agree with the above comment. Loss of network when in mon-mode is a downgrade in functionality from previous version. Minor aesthetic issues with Airmon-ng info displayed too. Excellent work though and very much appreciated.
